I am working on a design for a prototype. I was wondering if it is possible to wire a parallel battery pack consisting of 3-12v / 20ah which would equate to 12v-60ah, to another battery pack that is exactly the same through a capacitor to create 24v-120ah. Wiring parallel sacrifices voltage and wiring in series sacrifices ah. Is there a way around this or do I have to just buy 24v batteries and wire parallel to increase ah? I need 24v, however will also need a significant ah run time of 6 hours or so for my application. The above is just an example with ah until i decide exactly what size motor to use. Can anyone shed some light? I have tried to find my answer via research but cannot seem to do so.
Please let me know if you have any questions.
